Serum inflammatory cytokines IL-1, IL-6, and TNF-α as biomarkers for predicting the severity of pediatric hand-foot-mouth disease: A retrospective cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study aimed to explore the association between inflammatory cytokines and the severity of pediatric hand-foot-mouth disease (HFMD) and identify predictive biomarkers. We conducted a retrospective analysis of 240 children, including 120 severe HFMD cases and 120 mild HFMD cases admitted to the Linping Campus of The Second Affiliated Hospital of Zhejiang University. Comprehensive clinical data, including demographic information, clinical manifestations, and laboratory parameters, were collected upon hospital admission. Serum concentrations of interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-α) were quantified using enzyme-linked immunosorbent assays at days 1, 3, and 5 postadmission. Multivariate logistic regression was used to identify significant risk factors. Compared with the mild group, the severe group had a younger age (16.8 ± 10.5 vs 22.2 ± 12.2 months) and longer fever duration and hospital stay (all P = .001). Key laboratory indices (e.g., white blood cell count, blood glucose) were higher in severe cases (P < .001). IL-1, IL-6, and TNF-α levels in the severe group were significantly elevated at all-time points (P < .05), with receiver operating characteristic area under the curves of 0.87, 0.81, and 0.72, respectively. Age, fever duration, blood glucose, IL-1, IL-6, and TNF-α were identified as independent risk factors (all P = .001). IL-1, IL-6, and TNF-α are valuable biomarkers for predicting pediatric HFMD severity, with IL-1 showing the highest predictive efficacy, providing a basis for early clinical intervention.
